Boy, we've got the blues.

From unexpected suiting to fun socks (and everything in-between), the men's spring/summer 2012 runways were flooded with blue. The trick is to wear it together, but think complementary-monochromatic-chain-reaction, not solid-single-shade -- pair navy with cobalt, indigo with sky, and throw in a little tangerine for extra zing, or a white shirt for a breezy seaside look.

What's particularly nice about this trend is that, chances are, you already have a solid case of the blues. Use it. Cast a few new pieces (in bolder shades) and mix them in with your favorite navy cardigan, and that trusty striped dress shirt for a fresh spring look.
